Per hour on Windows, in each type's cheapest region. Typical spot: per pricing run of the last 7 days, the cheapest zone's spot price, averaged, as the finder shows it with that region selected. On-demand: the same region's price. Per vCPU-hour: the spot price, or without spot the on-demand price, per vCPU. Every region is under Prices by region.

The R5A memory-optimized instance family, first available in November 2018, features the AMD EPYC 7000 series processor (EPYC 7571) with an all-core turbo of up to 2.5 GHz. These instances are EBS-only, meaning they do not offer local NVMe instance storage. They provide up to 10 Gbps of network performance and are powered by the AWS Nitro System. R5A instances offer a cost-optimized alternative, with up to 10% savings over comparable R5 instances.

Network and EBS: peak bandwidth in Gbit/s, with the bandwidth the type sustains when it is lower. Local storage: the instance store, in decimal GB as AWS sizes it.

Atom feed for new regions

Each type's regions on Windows, cheapest first, with the same figures as the Prices table, and its price history: the daily mean of every zone and pricing run, over the last 15 UTC days. Each price column is tinted from its cheapest region (green) to its most expensive (red).
